Filed: 1980-06-06
Abstract: PURPOSE:To perform stable reproduction in great quantities with constant quality by coating the surface of a sheet of thermoplastic resin with resin, by press-contacting a stamper after sticking impalpable powder of diamond on the surface, and by carrying out a heat treatment. CONSTITUTION:On a sheet 1 of thermoplastic resin such as poly(vinyl chloride), another thermosetting resin, such as alkyd resin, is applied by spraying, etc., to form a film 2. After the application, it is left at the room temperature for a certain time to volatilize a volatile solvent, forming a thin viscous film. Impalpable powder of diamond 3 is sprinkled and then after part of it which is not in contact with the thermosetting resin is shaken off, the processes of pressurizing, heating and cooling are carried out to form polished grooves 4 in a desired shape. Thus, pictures of invariably stable quality are obtained through the reproduction of a high-density information carrier by a scanning stylus.

Title: Measurement of resistance of winding of teaser transformer of scott connection
Inventor: AZUMA SHINICHIROU
IPC: G01R27/02
Filed: 1984-04-16
Abstract: PURPOSE:To enable simple measurement with high accuracy, by using a double bridge type DC low resistance measuring instrument and respectively connecting one of two voltage terminals thereof and one of two current terminals thereof to the terminal parts of three-phase windings of a main transformer. CONSTITUTION:The voltage terminal P2 and current terminal C2 of a DC low resistance measuring instrument are connected to the terminal V of a teaser transformer 4 while a voltage terminal P1 and a current terminal C1 are respectively connected to terminals W, U of three- phase winding 2 of a main trans former 1. Then, the resistance of the winding part between the middle point of the three-phase windings 2 of the transformer 1 and the terminal U is set to DELTAX and the resistance of the winding part between the middle point 3 and the terminal V is set to DELTAN. The resistance X of winding to be measured at this time is calculated from a predetermined formula by adding and subtracting resistances N, n so as to bring the current flowing to a galvanometer G to zero. Herein, the resistance DELTAX is regarded as the internal resistance of a battery E and becomes regardless in measurement and the resistance DELTAN can be also disregarded in general because the resistance N is high. When the resistance DELTAN is not disregarded, if resistance DELTAM (wherein DELTAM/DELTAN=M/N) is also added to resistance M and the effect thereof is eliminated, the resistance X of winding can be measured without an error.

Filed: 1989-03-28
Abstract: PURPOSE:To generate a trigger signal always in a correct timing by receiving outputs of a delay line and a 1st amplitude comparator circuit at a gate circuit and suppressing the supply of the output of the said comparator circuit to a trigger circuit so long as the output of the delay line exists. CONSTITUTION:First and 2nd amplitude comparator circuits output outputs 202a, b when the input signal amplitude is respectively over a reference voltage. Upon the receipt of the outputs 202a, b from the 1st amplitude comparator circuit 2, the gate circuit 5 outputs a signal corresponding to the said input. However, upon the receipt of output 302 from the 2nd amplitude comparator circuit 3, the output 202b is suppressed by an output 401 of a delay line. An output 501 of the gate circuit 5 is inputted to a trigger generating circuit 1, which outputs a trigger signal in response to the input signal. Thus, the effect of superimposed noise is much suppressed and a trigger pulse is generated at a pulse front leading edge of the input signal without increasing the reference voltage.
